High Performance 1.67 High Index Single Vision Photochromic Lens HMC

1.67 High-Index Photochromic Lenses, these are advanced lenses that combine two key technologies. First, the 1.67 high-index material makes lenses significantly thinner and lighter than standard plastic, which is ideal for people with higher vision prescriptions. Second, they feature photochromic technology that enables the lenses to automatically darken to sunglass-like tint when exposed to UV light outdoors and return to clear indoors. They provide 100% UV protection, reduce glare, and offer a convenient, all-in-one vision solution.
